EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.0 under NVD CVSS v3. EPSS exploit probability: 5.1%, top 9% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In the python-libnmap package through 0.7.2 for Python, remote command execution can occur (if used in a client application that does not validate arguments). NOTE: the vendor believes it would be unrealistic for an application to call NmapProcess with arguments taken from input data that arrived over an untrusted network, and thus the CVSS score corresponds to an unrealistic use case. None of the NmapProcess documentation implies that this is an expected use case
